1 Claim.

My invention relates to seats for infants and the objects of myinvention are to provide an adjustable folding seat which can be readilyattached to and removed from the back of an ordinary household chair, orthe back of an automobile seat, church pew, waiting room seat, or anyother suitable support, which will hold an infant securely and safely,can be adjusted as to height and. can be folded up into a very smallcompass for traveling or when not in use; to provide such a seat whichcan be conveniently carried and used at church, at a picnic, at work ina garden, etc.

I attain these objects by the means illustrated in the accompanyingdrawings, in which,

Figure l is a'si-de elevation of my seat applied to a common form ofchair;

Figure 2 is a front elevation of the seat attached to such chair;

Figure 3 is a top or plan view of my seat attached to the back of anordinary household chair;

Figure 4 is a side view of my seat in folded position;

Figure 5 is a detail showing an alternate form of hinge to attach theback to the base;

Figure 6 is a detail showing a toilet form of base;

Figure '7 is a detail showing the back suspended on a tree.

Similar numerals refer throughout the several views.

My invention comprises a back or seat 2 with a base 5 having its rearedge pivotally united or hinged to the back preferably by short hingebars l screwed or otherwise firmly attached to the base by screws M andpivotally united to the back by pivot pins 1.2. Any other suitable formof hinge may be used, such as a piano hinge [9 shown in Figure 5.

Arms extend forwardl from the back and their rear ends are pivotallyunited to the back by bars 6 and pivot pins 6.2. The bars 6 are rigidlyunited to the back 2. Brackets 3.| are formed integral with the arms 3and extend downwardly therefrom and are arranged to bear against theback 2 when the seat is in open position, to form a firm support for thearms. At the front end of the arms a shelf or table 4 is mounted.necting bars or links 5 are pivoted which extind downwardly and theirlower ends are pivotally united to the side edges of the base I withpivots Ll.

When the parts are so arranged, the base I to similar parts To the frontends of the arms c'onmay be folded up against the back as shown inFigure 4. The arms also will fold up against the back and extend farenough above the back so that the shelf it will lie in substantially thesame plane as the back 2.

Various forms of support to secure the seat to the back of a chair,automobile seat or other support, may be utilized but I prefer a fixturehaving a pair of hooks l5 united by a crossbar. The hooks are adapted toembrace the top of a chair back or the back of an automobile seat,church pew, or other similar support. This fixture is preferably made ofa metal rod covered with a rubber or other soft covering.

At the middle of the crossbar I secure a peg or button i i. To the backI attach the lower end of a wide band 8 of fabric or other suitablematerial provided with spaced openings or eyelets is formed or securedin the free portion thereof. These openings or eyeletsare made of theright size to embrace the peg or button II whereby the seat may besuspended at the desired height above the seat of the chair to which itis attached, and when so adjusted, the seat M of the chair will form afootrest for the occupant of the folding seat. My seat may also besuspended from a garden fence or from a nail 2| driven in a wall, treeor post 22.

In the operation of my seat, it is first opened or unfolded. The hook isplaced in position upon the back of the chair or automobile seat, orother support. The back of my seat is placed in juxtaposition with theback of the chair or automobile seat at the desired height and theproper eyelet is then placed over the peg or button H in the crossbar ofthe hook. The child can then be seated upon the base and its weight willkeep the seat in its open position. The brackets 3.! under the arms 3will prevent the arms dropping down and the links or bars 5 will hold upthe front of the base.

The height of the appliance can be adjusted without removing the infantby detaching the strap 8 from the peg H and either lowering or raisingit and attaching the proper eyelet to the peg. The seat of the chair orpew or automobile seat will form a support for the feet of the child andthe arrangement of the base and the shelf will prevent the child fromdisplacing the seat by jumping or trying to stand. The weight of thechild pressing downward upon the strap 8 and the friction of the backwith the back of the chair or automobile seat will prevent tipping ortilting of my seat laterally. v

The chair [6 to which this seat may be attached will have a somewhatlarger base than the ordinary highchair and there will be no danger of achild tipping backward because his feet will be pressing downwardly uponthe front of the seat of the chair on which the appliance is mounted,and the back of the chair, if a solid back, or a crossbar l8 willprevent the base from moving rearwardly.

The base of my seat may be of either wood or metal and the back and basemay be padded if desired and the rear side of the back may be coveredwith felt or any other desired material to prevent scratching the chairor other support on which it is mounted.

To close the appliance, the base and arms are folded upwardly againstthe back, into a very small compass, as shown in Figure 4.

When at picnics, a convenient support may be made by driving a nail 2|into a tree 22 at the desired height.

My seat may be utilized as a toilet seat by cutting a suitable hole 20in the base as shown in Figure 6,.under which any suitable receptaclemay be placed upon the seat of the chair.

When my seat is thus mounted upon an ordinary chair, it will be heldstable more than an ordinary highchair because the legs I! of the chairwill afford a broader base for the chair to stand on than the legs ofthe ordinary highchair and the infants feet resting upon the seat Id ofthe chair will tend to prevent the chair from tipping over backward.

It is obvious that the size, form and arrangement of the parts may bemodified without departing from the spirit of my invention and I do notlimit my claims to the precise forms shown in the drawings.

If desired, a peg or pin may be secured in the back of a chair withwhich my seat is used, and in that case the band 8 may pass directlyover the back of the chair and have an opening or eyelet engaged withsuch peg or pin, then avoiding the use of the hooks.

I claim:

In a folding seat for children, a back, a seat pivotally united at therear of the seat to the lower end of the back, arms having their rearends pivotally united to the back and spaced above the seat, triangularbrackets united to the lower edges of the arms at the rear end thereofextending downwardly and arranged to bear against the back and supportthe arms when in open position, and pivoted'links connecting side edgesof the seat near the front thereof to the inner edges of the arms nearthe outer ends thereof whereby the arms will support the front of theseat when in open position.
